Add the order_field method to a function field

[Luciano Rossi]

Hi everybody!

I have a function field that depends on a many2one. I display this field
inside a tree view. I wanted to be sortable, so I found this doc[0] that
talks about it. The examples inside the code[1] are all about to sort
from a field that is from the same table. I will want to sort from a
different table, but I do not understand how to write that kind of code.

[0] http://doc.tryton.org/4.4/trytond/doc/ref/models/fields.html#ordering
[1] http://hg.tryton.org/modules/timesheet/file/tip/line.py#l287

PS: I also asked this question at irc, but nobody reply, and I need it
to leave. That's why I'm asking also here.

Thanks!

Hi,

Researching, I found a betters examples of what I was looking for and
help me to write the order_ method.

Hi Lucio,

We had also to do a sort on a function field.
Another example here: https://codereview.tryton.org/31881002/diff/330001/purchase.py#317 (line 317)
